Description

Technical Field

[0001] This application relates to the technical field of optical lenses, and in particular to a multi-dot array variable information sign lens module structure. Background Technology

[0002] Lens module structures play a crucial role in lighting equipment, significantly improving lighting efficiency and light distribution uniformity by optimizing light propagation paths. With increasing societal demands for energy conservation and environmental protection, high efficiency and precise light control in lighting equipment have become important industry trends. The design and application of various lens module structures not only meet the lighting needs of different scenarios but also drive lighting technology towards greater efficiency and energy savings. Especially in the design of LED placement and its integration with reflectors, the industry is continuously exploring new solutions to enhance overall performance.

[0003] Existing lens module structures still have shortcomings in terms of LED layout and compatibility with reflectors. Currently, most methods involve mounting LEDs one by one onto the lamp board to fix them in place. While this improves the flexibility of LED assembly, the assembly precision between the LEDs and the lamp board affects the compatibility between the LEDs and the reflector, resulting in unstable light reflection and reduced overall lighting performance. Utility Model Content

[0004] In order to improve the matching accuracy of the LED beads and the reflector and improve the lighting performance of the lens module, this application provides a multi-matrix variable information sign lens module structure.

[0005] The multi-matrix variable information sign lens module structure provided in this application adopts the following technical solution:

[0006] A multi-matrix variable information sign lens module structure includes a base, a light panel, and a reflector. The light panel includes a plate body and several LEDs. The LEDs are evenly distributed on the plate body. The plate body and the LEDs are integrally formed. The plate body is connected to the base. There are several plate bodies, which are spaced apart along the length of the base. The reflector is connected to the side of the plate body away from the base. The reflector has mounting holes. The number of mounting holes is the same as the number of LEDs and they correspond one-to-one. The LEDs are embedded in the mounting holes.

[0007] By adopting the above technical solution, the integral molding of the board and the lamp bead reduces the assembly process between the lamp bead and the board, improves the fitting accuracy between the lamp bead and the reflector, and ensures that the mounting holes correspond one-to-one with the lamp bead, so that the light emitted by the lamp bead can be effectively reflected and focused, and the lens module improves the lighting performance.

[0008] Preferably, the plate body is provided with a plurality of connecting holes, which are distributed at intervals along the circumference of the plate body. The base is provided with fixing holes, the number of fixing holes being the same as the number of connecting holes and corresponding one-to-one. The connecting holes are used for bolts to pass through and be threaded into the fixing holes. The reflector is provided with clearance grooves, the number of clearance grooves being the same as the number of fixing holes and corresponding one-to-one. The clearance grooves are used for bolt heads to be embedded.

[0009] By adopting the above technical solution, the connecting holes and fixing holes correspond one-to-one, which facilitates the fixed connection between the lamp panel and the base by bolts. The reflector is provided with a relief groove, which facilitates the reflector to fit the lamp panel, thereby improving the overall reliability and practicality of the lens module.

[0010] Preferably, a positioning strip is connected to the side of the plate near the base, and a positioning groove is provided on the side of the base near the plate, with the positioning strip embedded in the positioning groove.

[0011] By adopting the above technical solution, the plate is provided with a positioning strip, which is embedded in the positioning groove so that the connecting hole is aligned with the fixing hole. This facilitates the subsequent bolting to fix the lamp plate and the base, reduces the possibility of relative movement between the lamp plate and the base in the direction perpendicular to the thickness of the base during the connection process, simplifies the assembly process, and improves assembly efficiency.

[0012] Preferably, a plurality of connecting posts are connected to the side of the plate away from the reflector, and the plurality of connecting posts are distributed at intervals along the circumference of the plate. The base is provided with connecting grooves, the number of connecting grooves being the same as the number of connecting posts and corresponding one-to-one. The connecting grooves are used for the connecting posts to be embedded. The outer periphery of the end of the connecting post away from the plate is provided with a chamfer, and the chamfer is used to abut against the wall of the connecting groove.

[0013] By adopting the above technical solution, the chamfered abutment to the groove wall of the connection channel plays a guiding role in the installation of the lamp panel, making it easier for the positioning strip to be aligned with the positioning groove and embedded in the positioning groove. This improves the stability of the connection between the lamp panel and the base, reduces the possibility of relative movement between the lamp panel and the base in the direction perpendicular to the thickness of the base during use, and improves the reliability of the lens module.

[0014] Preferably, the base has a first weight-reducing groove on one side near the plate and a second weight-reducing groove on the other side of the base.

[0015] By adopting the above technical solution, the base is provided with a first weight reduction groove and a second weight reduction groove, which effectively reduces the weight of the base, thereby reducing the weight of the entire lens module structure, making it easier to install and transport, reducing the amount of materials required for lens module production, and reducing production costs.

[0016] Preferably, the bottom of the first weight-reducing groove is connected to a first reinforcing rib, and the two ends of the first reinforcing rib are respectively connected to the wall of the first weight-reducing groove.

[0017] By adopting the above technical solution, the bottom of the first weight-reducing groove is connected to the first reinforcing rib, and the two ends of the first reinforcing rib are respectively connected to the wall of the first weight-reducing groove, thereby effectively improving the structural strength of the base, reducing the possibility of deformation or damage to the base due to external force, and improving the service life of the lens module.

[0018] Preferably, it also includes connecting threaded sleeves. The base has a plurality of grooves on the side away from the plate. The plurality of grooves are distributed at intervals along the circumference of the base. The number of connecting threaded sleeves is the same as the number of grooves and corresponds one-to-one. The connecting threaded sleeves are embedded in the grooves.

[0019] By adopting the above technical solution, several grooves are provided on the side of the base away from the plate. The grooves are distributed at intervals along the circumference of the base. The connecting screw sleeves correspond one-to-one with the grooves and are embedded in the grooves, which improves the stability of the connection between the base and other components and improves the installation flexibility and reliability of the lens module.

[0020] Preferably, the reflector is connected to a ring plate on the side near the reflector strip. The number of ring plates is the same as the number of mounting holes and they correspond one-to-one. The ring plates are arranged around the mounting holes, and the axis of the ring plates coincides with the axis of the mounting holes.

[0021] By adopting the above technical solution, it is easier to protect the LED beads embedded in the mounting holes and improve the service life of the LED beads.

[0022] Preferably, a reflective strip is connected to the side of the reflector away from the plate, and a reflective surface is provided on the side of the reflective strip away from the plate, and the reflective surface is inclined.

[0023] By adopting the above technical solution, the reflective strip has an inclined reflective surface, which reflects the light emitted by the lamp beads, thereby improving the utilization rate of the light emitted by the lamp beads and improving the lighting effect.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The integral molding of the board and the LED beads reduces the assembly process between the LED beads and the board, improves the fitting accuracy between the LED beads and the reflector, and ensures that the mounting holes correspond one-to-one with the LED beads, so that the light emitted by the LED beads can be effectively reflected and focused. The lens module improves the lighting performance.

[0026] 2. The plate is equipped with positioning strips, which are embedded in positioning grooves to align the connecting holes with the fixing holes. This facilitates the subsequent bolting of the lamp plate and the base to fix them together, reduces the possibility of relative movement between the lamp plate and the base along the direction perpendicular to the thickness of the base during the connection process, simplifies the assembly process, and improves assembly efficiency.

[0027] 3. The chamfered joint with the groove wall guides the installation of the lamp panel, making it easier for the positioning strip to align with the positioning groove and embed the positioning strip into the positioning groove. This improves the stability of the connection between the lamp panel and the base, reduces the possibility of relative movement between the lamp panel and the base along the direction perpendicular to the thickness of the base during use, and improves the reliability of the lens module.
